If carbon has an atomic mass of 12.011 amu and oxygen has an atomic mass of 15.999 Amy what is the molecular mass of carbon dioxide?
The molecular mass of carbon dioxide (CO₂) is calculated by adding the atomic mass of one carbon atom and two oxygen atoms. This is done as follows: 12.011 amu (for carbon) + 2 × 15.999 amu (for oxygen) = 12.011 amu + 31.998 amu = 44.009 amu. Therefore, the molecular mass of carbon dioxide is approximately 44.01 amu.
Can explain how to get the molecular of mass of CO2?
Just add the grams per mole mass of the constituent atoms. C---carbon = 12.01 grams 2 O---2 oxygens = 16.0 grams each, or 32.0 grams ------------------------------------------------------------------------+ = 44.01 grams per mole for CO2 ( carbon dioxide )
Where does most of the mass of glucose come from?
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
What is the atomic mass of carbon 12?
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
What is the mass of one carbon atom?
the atomic mass carbon is 12.011 g/mol 12.011/mol = the mass of one atom 12.011/6.022x10 raised to the power of 23 this equals 1.994520093 x 10 raised to the power of -23 this is the mass of one atom of carbon in grams.
What is the percent of carbon in carbon dioxide?
In terms of proportion of molecules that are carbon, 33% (formula: CO2 which means that there are 2 oxygens and 1 carbon). If you mean in terms of mass, then carbon is 27.27% of the molecule (Two oxygens at a molecular mass of 16 each, and one carbon at a molecular mass of 12) by mass.
What is Carbon Dioxide's Atomic Mass?
First of all, carbon dioxide is a molecule and hence the question should be: What is the molecular mass of carbon dioxide? and the answer is 12 + (2 x 16) = 48
What is the mass of a carbon dioxide molecule?
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
What is the total mass of the carbon in 2 molecules of butane?
4 Carbon atoms in one molecule of Butane, times 2 because of two molecules, time the weight of one Carbon atom, which is 12 amu's (an amu = atomic mass unit, also known as a Dalton) equals 96 amu's.
How many protons does an atom of Carbon have if it has a plus 2 charge and a mass of 15?
An atom of Carbon with a mass of 15 and a +2 charge must have 13 protons. This is because the atomic number of Carbon is 6, so a neutral Carbon atom would have 6 protons. Since the atom has a +2 charge, it has lost two electrons, making it a cation, and giving it 2 more protons than electrons.
Can explain how to get the molecular of mass of CO2?
Just add the grams per mole mass of the constituent atoms. C---carbon = 12.01 grams 2 O---2 oxygens = 16.0 grams each, or 32.0 grams ------------------------------------------------------------------------+ = 44.01 grams per mole for CO2 ( carbon dioxide )
What is the mass percent of carbon in dimethylsulfoxide?
C2H6SO:C-2 (12.01)= 24.02H-6 (1.01)= 6.06S-1 (32.06)= 32.060-1 (16.00)= 16.00---------------------------= 78.14 g%C in C2H6SO= 24.02/78.14 (total mass) --> =.30739 (*100)Answer: 30.7% Carbon in dimethylsulfoxide.
What is the percent of carbon in C2H12O6?
The formula given shows that each molecule of the substance contains two atoms of carbon, twelve atoms of hydrogen, and six atoms of oxygen. Therefore, the gram molecular mass of the substance is twice the gram atomic mass of carbon plus 12 times the gram atomic mass of hydrogen plus six times the gram atomic mass of oxygen. In numerical terms, this is [2(12.011) + 12(1.00794) + 6(15.9994)] or 132.11. (Only five significant digits are justified, because only five digits are given for the atomic mass of carbon.). Therefore the mass fraction of carbon in the substance is 24.022/132.11 or 0.18183. Multiplying by 100 yields 18.183 % of carbon in the substance.
Where does most of the mass of glucose come from?
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
What is the atomic mass of carbon 12?
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
What is the percentage mass of oxygen in carbon dioxide?
The proportion by number of atoms in carbon dioxide is 1:2. The atomic weight of carbon is 12.011 and the atomic weight of oxygen is 15.9994. Therefore, the proportion by mass of carbon to oxygen in carbon dioxide is 12.011/(2 X 15.9994) = 0.37536 or 37.536 %, to the justified number of significant digits.
What is the atomic mass of carbon?
The atomic mass of carbon is approximately 12.01 atomic mass units.
